Thanks guys. It is what I was kind of thinking but I wanted to get more opinions. Do you guys try and get to the big water to hunt them in these cases, or is it better to turn to the fields when smaller ponds are frozen?

Once it's cold,, again in my experience, they're going to corn and possibly twice a day, and it doesn't seem to matter the distance needed to travel between roost and food as long as it's a good source and you (or others) don't try shooting them every day.

I've witnessed flocks of geese that will keep an open spot of water in fridgid temps on a good roost lake by going out to feed in shifts so that there's always birds in the waterhole.
